| Popis: |
The decomposition result of empirical mode decomposition (EMD) may be incorrect if some frequency components of original signal are close to each other. To avoid illusive result and get an exact one suiting for analysis, a harmonic wavelet filtering can be used before the EMD is performed. In the course of application of harmonic wavelet filtering, data was decomposed subsection overlapped to overcome the edge effect of usual digital filter that is caused by data truncation. The experiments showed its feasibility and validity in application of real-time processing. |
